cpplib.c (init_parse_option): Renamed to cpp_options_init.

* cpplib.c (init_parse_option):  Renamed to cpp_options_init.
(push_parse_file):  Renamed to ...
(cpp_start_read):  Change to return 1 on success, 0 on failure.
(init_parse_file):  Renamed to cpp_reader_init.
* cpplib.c (cpp_start_read, cpp_handle_options, cpp_finish,
parse_goto_mark, parse_move_mark):  Use cpp_fatal rather than fatal.
* cpplib.c (newline_fix):  Remove unused function.
